Answer:

The first part is perfect. Fix the second inequality.

Explanation:

The second inequality is:

4x - y > -3

Subtract 4x.

-y > -4x - 3

Multiply by -1 remember when multiplying (or dividing) by a negative number you must REVERSE the inequality symbol.

y < 4x + 3

Your line looks great, but make it dashed. And then the shading will be below the dashed line. This creates the solution set in the triangular area in the middle bottom of the graph. The point they are asking for is not the point of intersection, it is any point in the bottom triangle, which is the doubly shaded solution set area. Use (0, -5) for example.
